Going to be interesting to see what the forensic engineers find. There are so many possibilities. You need to look at things on site to fully determine the cause of such a failure. Glad there was no one on or near it when it failed. It could have been horrid.
Note to self: remove gondola cars at night so they don't fall.
This is why bridges now cover the bottom 10-15 ft of support cable at the roadway level.
They used to have a section of the main suspension cable of the Verranzano Bridge at that little park right before the bridge in Brooklyn. As I recall, they were parallel strands on the inside, not twisted. At some point maybe they got nervous about advertising the structure and removed it.
